Ok so, you have to remember there are mostly just new people on here looking for answers and then once they figure out the game they don’t check the sub often. So that’s why you get all kinds of crazy advice about infantry and armor etc.

The guy above you - dude08 is one of the few exceptions, he’s actually a good player - but his answers are always so short and to the point (the opposite of me lol )

The answer to your question, you don’t . Unless you have a big numbers advantage , you simply shouldn’t be taking infantry vs infantry fights or armor and infantry… and if you have a big numbers advantage then any infantry will do.

You kill ground and armored units with artillery from a distance or you kill them from above with your air force, then you move your ground troops in.

This way you take no losses and progress much faster. It’s totally fine to make motorized inf instead of national guard. You will see the top players make both, what you won’t ever see are the top players wasting resources on expensive infantry and armor because they know it’s better spent on more efficient units.

I hope that makes sense :)

Remember with artillery the damage is applied once then even though it fires for the next hour no damage value is applied again until that hour is up. So you hit with your artillery and if they chase to close the distance you run the opposite way for the next 59 mins to maintain distance then turn and fire again, rinse and repeat.

This strategy works best when you combine the artillery with SAMS and radars.
